Oh to not have to worry about cleaning the **** things!
I'm about 90% complete on mine now - just need to go gravity fed to cut out the weekly pre filter clean out (which is extremely NASTY!)
I've not concreted on the left of the bottom pond as this is where I'll be replacing pipework at some point - I'll add a bog filter at some point too as anything I put in the pond gets eaten in short order!
Here's one of everyone in and enjoying themselves
I love your set up. This is what I dreamed for but the DH wouldn't let me spend the money You've done a great job!
